Wireless doorbell systems that have a kinetic-powered button (i.e. no battery) exist, e.g. https://www.amazon.com/gp/product/B0929729L1
Wireless relay receivers also exist, e.g. https://www.amazon.com/gp/product/B0B125VLNB
These products often use the 433 MHz band. Are there any that actually work together? What I really want is a kinetic-powered doorbell button that triggers a relay instead of a chime box.
The problem with light switches is that they are latched relays that typically only output line voltage, whereas I need a momentary relay that passes through 16V AC from the doorbell transformer. Do you know if some way to adapt this to my needs?
